Quote rlivermore Replybullet Topic: DateDiff formula help
     Posted: 01 Mar 2013 at 6:46am
CR 9.5 Pro, SQL 2008 database
 
Wanting to compare two dates/times using the formula below but am getting the following error "remaining text does not appear to be part of the formula" and it highlights the second and third formulas. Where am I going wrong?
 
NumberVar logDiff = DateDiff('n',{tblSOLogs.StartDateTime},{tblSOLogs.EndDateTime})
NumberVar hours = logDiff \ 60
NumberVar minutes = logDiff mod 60
 
Sample data:
John Doe - Labor - 2/4/13 7:45 - 2/4/13 8:00 (logDiff = .25)
John Doe - Labor - 2/4/13 8:30 - 2/4/13 10:00 (logDiff = 1.50)
John Doe - Labor - 2/4/13 10:45 - 2/4/13 11:15 (logDiff = .50)
Sub Total: 2.25

First off, when assigning a value to a variable you need to use ":=" instead of "=".  Secondly, when doing a multiple-line formula in Crystal, you need to end each line with a semi-colon - ";".
Also, is it possible for either of the fields to be blank?  If so, you'll need to add some null handling to the formula.  Something like this:
 
NumberVar logDiff := 0;
 
if not IsNull({tblSOLogs.StartDateTime}) and not IsNull({tblSOLogs.EndDateTime}) then
 DateDiff('n',{tblSOLogs.StartDateTime},{tblSOLogs.EndDateTime});

Thank you very much for your help! The formula now looks like this...
 
If not IsNull({tblSOLogs.StartDateTime}) and not IsNull({tblSOLogs.EndDateTime}) Then
NumberVar logDiff := DateDiff('n',{tblSOLogs.StartDateTime},{tblSOLogs.EndDateTime});
NumberVar hours := logDiff \ 60;
NumberVar minutes := logDiff mod 60
 
I inserted the formula into the report and it's not calculating correctly and am not sure where I've gone wrong, sample output below:
 
Mark D - SO   - Log Reason - Start Date  -  End Date    -   Diff
             112    Shop             2-4-13 7:55   2-4-13 9:15    20:00
             115    Travel           2-4-13 9:15   2-4-13 10:15   0:00
             118    Labor            2-4-13 10:15 2-4-13 15:00   45:00

What version of Crystal are you using?  Please go to Help - About and post the full version number.

This is a tough one... I think this was an issue in Crystal 10 that was fixed in a service pack.  But Crystal 10 is out of support and I don't know of anywhere to get the patches for it.
 
I think I know another way to do this.  Are any of your end dates on a different day than your start date?

What you are getting as your output appears to simply be a representation of the minutes (without hours) and I would bet this is because it is the last calculation.
I think you will need one more calculation like:
StringVar elapsed := totext(hours, 0, "")& ":" & totext(minutes, "00",0,"")

That seemed to do the trick, thank you VERY much! Lastly how would I go about totaling the logDiff formula for each rep?

Just curious if anyone is willing to share as to how I can get subtotats for each rep with logDiff formula?
